11 The United States Since the Cold War

Politics and economic change in the 1980s

Ronald Reagan’s 1980 election reflected a Conservative political shift toward lower taxes, less federal regulation, stronger defense spending, and a more assertive stance against communism. His administration reduced some taxes and regulations and increased military spending. Supporters argued that these policies encouraged economic growth, while critics emphasized rising federal deficits and unequal gains.

The economy continued to move away from manufacturing toward service industries, affecting many industrial communities. Personal computers also became more common in homes, schools, and workplaces, foreshadowing later digital changes. By 2000, 42 percent of U.S. households had at least one member using the Internet at home.

The Cold War ends

The Cold War’s final years involved both confrontation and negotiation between the United States and the Soviet Union. Soviet leader Mikhail Gorbachev introduced reforms and allowed political change in Eastern Europe, where communist governments lost power. The Berlin Wall opened on November 9, 1989, becoming a symbol of the collapse of Europe’s division. The Soviet Union dissolved in December 1991, ending the superpower rivalry that had shaped U.S. foreign policy since World War II.

The end of that rivalry did not end international conflicts. In 1991, after Iraq invaded Kuwait, the United States led a broad international coalition that forced Iraqi troops out. The Gulf War demonstrated U.S. military strength while showing that conflict continued in the post-Cold War international landscape.

Globalization and political change in the 1990s

During the 1990s, international trade expanded, while the Internet and personal computing transformed communication and business. The North American Free Trade Agreement (NAFTA) took effect in 1994 and deepened economic ties among the United States, Canada, and Mexico. Supporters anticipated new markets and jobs; opponents worried that competition and shifts in production could harm some workers and communities. Growth in service and technology sectors accompanied continuing losses in manufacturing employment.

Political conflict also remained intense. President Bill Clinton, a Democrat, worked with a Republican-controlled Congress on measures including welfare reform. Partisan disputes over policy and presidential conduct culminated in Clinton’s impeachment by the House of Representatives in 1998. The Senate acquitted him, and he remained in office.

Civil-rights protections expand

The Americans with Disabilities Act was signed in 1990. It prohibited discrimination in employment, public services, public accommodations, and transportation, establishing broad federal protections for people with disabilities.

Terrorism and war

On September 11, 2001, al-Qaeda terrorists hijacked aircraft and attacked the World Trade Center and the Pentagon. A fourth plane crashed in Pennsylvania after passengers resisted. The attacks killed nearly 3,000 people and reshaped U.S. security policy.

The United States invaded Afghanistan in 2001 to target al-Qaeda and remove the Taliban government that had sheltered it. In 2003, the United States invaded Iraq, beginning a prolonged and divisive war. The 9/11 Commission later concluded that Iraq had not planned or carried out the September 11 attacks.

Economic crisis and domestic policy

A recession began in December 2007 amid a housing and financial crisis. Falling home prices and financial-market instability contributed to a severe downturn. Unemployment rose, and many households lost homes or savings. The recession ended in June 2009, but recovery was slow. The crisis strengthened demands for government action and reform of financial regulation.

Barack Obama’s 2008 election as the first African American president was a milestone in U.S. history. His administration responded to the economic crisis and enacted the Affordable Care Act in 2010, a major expansion and restructuring of health-insurance coverage. The law became a focus of continuing political debate over the reach of federal authority and the role of government in social welfare.

A changing United States

From the 1980s to the early 2010s, the Cold War ended, and the U.S. economy became more technology- and service-oriented. Political divisions persisted through changing administrations. The Americans with Disabilities Act and the Affordable Care Act marked major domestic policy developments, while the September 11 attacks, wars in Afghanistan and Iraq, and the Great Recession reshaped national security priorities, the economy, and political debate.
